I hate to say it, but read the screen where you got the drivers :D
Go back to:
http://printer.konicaminolta.com/support/current_printers/mc2300dl_sup.htm#drivers
When you get to the proper drivers for your OS there is a link just aboive the download links that says Installation Instructions. When you point at it a pop up appears which tells you, oddly enough, how to install the drivers. Basically run the exe file you downloaded and unzip the files into a directory then run setup.exe.
:D
